RAILVAY CAR.

Application filed January 20, 1922. Serial No. 530,629.

To allwkomt'tmayconcern: g i

Be it known that l, H GH .W. SAN-- FORD, a citizen of the United States, residing. at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Railway Cars, of which the following is a specification, reference belng had to the accompanying draw- Tfy improvement relates particularly-torailway cars which are intended to dump their loads downward through the bottom of the car by the opening of hinged doors which form the bottom of the, car. car of this type, reference is made to my Letters Patent of the United States No. 1,268,390, granted June 431918, for an improvement in railways. The object of the present improvement is to provide for such a car a different form of latch'mcchaniem to hold the rear door of the car in the closed position. In said Letters Patent,an impor tant part ofthe latch mechanism is sup ported by the end wall of the car body; that isto say, two angle levers are pivoted to the end wallof the car body, and each such lever has a downward-directedarm on which is a hook adapted to engage a tongue extending rearward from the rear edgeof the rear bottom door. It will be understood that the relation between the fulcri of said levers and said tongues should be constant (when the door is closed). But it has been found in practice that the end wall of the car does not constitute as substantial a support for this wall of the car body issheet metal; for suchmetal may become battered o1 bulged inward or outward. Furthermore, at times a heavy impact against the end wall of the car body may force saiden'd wall inward levers maybe used if desired.

positioning of said Letter Patent mentioned above.

side sill rests a side wall, C. At each end In the accompanying drawings,

Fig. 1 is an end elevation of a railway car embodying my improvement; I i i Fig. 2 is an upright section on the line 22,-of Fig. 1; Y I s Fig. 3 is a part of the same section drawn to a larger scale;

4 is a detail end elevation, parts being broken away; i

Fig. 5 is a detailperspective, parts being omitted; I

Fig. 6 is a perspective of the casting forming the downward-directed arm of the angle lever, said casting being laid into the hori- Zontal position to show its rear face.

Referring. to said drawings, A, A are track rails- A A are ordinary car wheels supporting an axle, A Said axle supports side sills, B. B, only one of which is shown: andthe ends of the side sills support end sills, B only one of which is shown. The

side sills and the end sills form the rectanular frame similar to that described'in my On each of the car an end wall, G has its ends jOlHQCl to the ends of the side walls. Doors, D, D. form the bottom of the car. The

rear door, D, the one at the right in'FigLQ,

has its forward end hinged to the rear axle A2 T F. 9 f a in .r 1g. J said door is shown in the closed orraised position, and it is to be held in said position until it is desired to dump the load. Onthe rear edge, of said door is a wrist,,D which projects rearward ap proximately horizontally. From said wrist a body, D extends downward and forward against the lower face of the door and is secured to the door by means of rivets, D whereby said wrist is made rigid.

To the inner or forward face of the ad jacent (the rear) 'end sill, B is applied a compound standard, rising above said sill and composed of a straight member, E, and a bent member, E The lower ends of said members overlap each other and are secured to the end sills by rivets, E extending through said two members and the adjacent upright wall of the end sill. The upper ends of the standard members, E and E,

are separated sufficiently to receive between them the angle lever comprising the horizontal arm, E and the shorter, downward- E The angle lever is supported on a journal, E extending horizontally through the members, E and E and said angle lever. The upper face of the hook, E is shown slightly concave or downward-curved, whereby the wrist, D will make such a seating on said hook as will require a slight lifting of said wrist to permit the hook to move sidewise from beneath said wrist. Further tendency toward maintaining the engagement between the hook and said wrist is had through the downward pressure, by gravity, of the longer horizontal arm, E of the angle lever. A. further ad dition to such tendency is had through the contracting coiled spring, E which has one end secured in the eye, E and has its other end secured in a bracket, ll, secured to the adjacent end wall brace, F. It is to be understood that this spring may be omitted when the downward pressure of the horizontal arm, E is sufficient to make and maintain engagement between the hook, E and the wrist, D

in the form shown in the drawings, the arm, E and the downward-directed arm, E are separate pieces, the arm, E being a straight metal bar and the other arm being a casting having at its upper end a horizontal channeled head, E the channel of which receives the arm, E Bolts or rivets, E extend through said head and the bar, E to secure said members immovably to each other.

The arm, E extends through a guide structure formed by the end wall brace, F, and the auxiliary piece, F The lower end oi? the brace is secured to the end sill by a bolt, F and the upper end of the brace is secured to a horizontal metal strap, G on the outer face of the endwall, C y means of a bolt, F The auxiliary piece, F is secured to the brace, F, by means of bolts or rivets, F The arm, E extends between the brace, F, and the auxiliary piece, F

The rear door, D, may be raised into the closed position by an attendant or automatically by such a track cam as is described in my Letters Patent above-mentioned. The door is to be released by lifting the outer or free end of the lever arm, E This may be done by the attendant when the car has reached the place at which its load is to be dumped; or said arm may be lifted automatically by means of a relatively stationary member placed beside the track at the dumping station and adapted to engage the lower edge of the arm and push said arm upward during forward movement of the car on its arrival at the dumping station. as described in said Letters-Patent. It is to be understood that if this automatic operation is desired, the arm, E is to be made long enough to reach horizontally outward beyond the side of the car far enough to be engaged by such a relatively stationary member.

In addition to the advantage in avoiding the uncertainty of position of the fulcrum of the angle lever when said fulcrum is sup ported by the end wa-l of the car body, the present structure has the advantage of permit-ting the use of latch mechanism which is of the same form, although the side and end walls of the car body are varied. Furthermore, by applying the angle arm support to the end sill, the latch mechanism may be applied to a car before the side and end walls are put on the car. Then said walls may be applied by the purchaser in the form best meeting his needs after he receives the car.

The several parts of the latch mechanism are preferably so proportioned as to avoid extending the hook, E below the end sill, Il and below the door, D, when the latt r is closed. Thus the hook will be prevented from making contact with objects lying on the track when the car is moving either for ward or backward.
